ALEXANDBE TREPREAU. OF JOINViLLE-LE-PONT, FRANCE.

APPARATUS FOR HEATING WATER.

Auplication filed February 18, 1911.

To all wrwm it may concern:

Be it knoufnthat I. Annxaanun' a citizen of the'French Republic, residing at Joinvilledeiont, in France. have inand useful Improve- .tnents in Apparatus for Heating ater. of which. the'following is a specification. ref erence being bad therein to the accompany iu'g drawing.

This invention has reference to an apparatus for heating watcrby means of an electric current which is branched for example from, a' lighting circuit, or from a special circuit. The current is utilized for Tmirumu.

heating metal resistances wound around one or more glass tubee through which the water to be heated is conducted.

The apparatus can water. tap by screwing or soldering it to the the water is turned on, after having turned on the current, this water will be delivered at a. temperature which can be regulated by varying the rate of delivery. tnelower the rate at which the wateris delivered the higher will be the temperature. 7

This heatingapparatus can be employed for heating large quantities of water. for example for forming bath-geysers. "In this 80 case a great number of tubes will be pro- Yided and will be arranged inseries or in parallel and the ap )aratus thus constructed will be neither expensive nor occupy much space.

I shall now describe myfinvention with reference to the accompanying drawings showing various forms of construction of the present invention, inwhichi Figure -1 is an outside View of an ap- Jaratus fitted ,to'an. ordinary water tap.

T for example. I sistance wires 9, so as to form three circuits or branches of the main conductors 9. 10 connected to the switch 11.

i The tube t is attached at its upper por-- tion' to the connection E2. and its third branch "I terminates in a constricted portion 12 reaching to the center of the metal tube 3. slightly above the outlet 13. formed in the baseof the conical part of the end of the said tube 3. v In this condition the tap 1 is turned on and water passes through the tube 4. the resistance 8 heing'p'laced in circuit, and water will be obtained up to a temperature of about -centigrade with a current for example. of 4 ainpere-'=..

According to the method of construction shown in Fig.3 the 'water tap 14 is joined to a connection, 16 by a flexible tube 15. The tap 14 and the connection lti are fitted to a walh for example. and the bent tube 1'4 is mounted on the connection 16 and terminates at its other end in a head 18 to which is fitted .the metal tube 3 containing the tubes and the heating element.

applicable for heating water for baths.

Figs-4. l and 5 show 'a modified form of construction referring to 1a special method of manufacturing and mounting the glass tubes. The latter are in this-casc'prcscnt to the number of three. 20. 21 and 12;. although there might also be five or more. These tubes are quite straight and are mounted in the following manner: The first tube "20 through whichthe water passes is connected by a flexible tube 23 to the connection shown at 18 in Fig. 3. This connection is mounted on the cap 24 which covers the upper part At its lower portion this tube '20 is connected to the adjoining tube 21.by means of metal fittings .26. These metal fittings or cups are threaded at their interior. but at their lower portion are proes. An india rubber lass tube enga a a tween'thc glass tube diid around which are wound re I The elem. tr o-current is supplied through the wires 19. This arrangement is more particularly the metal littin, 2a, and i. surmounted. by a metal wadier 3H. whii'h van be tightened up by were in down the nut 30. This lat ter voinprra es the lli'llet rubber whieh lirnily holds the glass tube and forms a safe ti lit joint. The first inrtal titling or cup 2b is eonneeted to the adjoining eup by means of a small enrved Popper tube 31. The two remaining tubes' 2! and 22 are eonneeted at their upper portion by similar fittings to the preredingr one, and the tube L52 earries at its lower extremity a single inetal fitting or rap 3'2 which is terminated by a. straight tube 33. passing through the lower portion of the outer tube 25 the opening of Whieh is provided with a. fiber washer urinating; the tube The tubes 20, 2t and 22 are provided with resistance wires 35, as described above, and the current conducting mains are at'tached to the binding posts 36 and 3?, one of said niains having an extension 38 wrapped in 'oesto.- and the other an extension 39 also [P991 in asbestos. These two wires 38 and 35 are ronnerted to current Conducting "maths 40 contacting with the wires 35. the hinting portion is thus formed by all the tubes and the Wires. andin order to inaulate the wire from the metal casing 25, a uiitable rolled sheet of asbestos 25 is arranged on the interior of the casing.

The Feed water pressure is controlled or i rnited by tapering downwardly the water dart through the head 18 and is caleulated so as to give a slightly greater supply than that required. It 18 this part which receives end cheeks any excessive pressure.

The above described arrangement of the glasstubes has the advantage of always braving the apparatus full of water so that it' a current is connected up before opening the tap the apparatus will not work use" lessly.

Fig. (3 liagrannnatiea lly shows in section he arrangement of the tubes for an appara tus for supplying large quantities of water and intended to serve as a bath geyser. These tubes are presentto the number of 28, and are arranged in four groups of seven mounted in series and indicated at 41, 42.

34, thereby in l t and 44. The inlet of water is eltei'ied for earh group illltdtllligl to the arrow and the outlet aevording to the arrow B. 'lhese series of tubes are grouped in a sin gle apparatus in forming a easing. This easing is of ret'taugular or muare shape. and oeeupies but little space. and the tubes are arranged and. t ed with rurrent in any manner. and by means of any suitable tit.- tings in aerordant'e with the above prinripal indii-ations. without thereby deviating from the prinr-iple of the invention. The prinripal advantage of these various: apparatus are as follows:--Siniplieity of mounting. easy UXUlHLHglIiI of one of the elements or heating tubes. taeility of grouping the tubes in series. in parallel. or in seriesparah lel. an apparatus wrupying but little spare. and capable of being employed for anyquair tities oi hot water. without loss of heat by radiation. and serving for heating any liquids.

Haring fully desrribed my invention. what I ('lfllltl as new. and desire to serure by Letters Patent is:--

l. Anmleetrie a 'iparatus for heating water. eoinprieing a ovlinderfa head thereon adapted to'be ronnerterl to a water tap and having a. downwardly tapering duet, a pin rality ot' iunueonducting water tubes eon neeted to form a (ontinuous tube resistant-e coils in circuit on said tubes and a flexible ronneetion between said head and said tubes.

2. An electric apparatus tmnhealing wa ter. eoiuprising a cylinder. water tubes having! inlets and outlets therein. resistanee (oils in eireuit on said tubes. inwardly threaded Pup-lilte fittings to form seats for said tubes. tiiiilSl'lC bands between said fittings and the lower ends of said tubes. washers on said tubes above said bands and outwardly threaded nuts to engage said fittings for the purpose stated.

in testimony whereof I aflix my signature in the presence of two witnesses.
